First, if your 2-hour PP after dinner is as low as 108, you might be going low overnight. Are you checking right before bedtime? This is the first thing I'd do...if your bedtime numbers are down around 80-90, you might be experiencing lows overnight, which means you'd need a small bedtime snack.
But, if your bedtime numbers are not too low, it's possible that you are having Dawn Phenomenon. The only way to test this, unfortunately, is to wake up several times at 3:00 AM, 4:00 AM and possible 4:30-5:00 AM and test. If your numbers at those times are reasonably normal, but not too low (not below 70), then it is Dawn Phenomenon. In that case, it's possible that some NPH insulin at bedtime, which peaks about 4-6 hours after you take it, could lower those morning numbers or, you could take a unit or two of rapid-acting insulin upon awakening. On the other hand, if you test at those hours and your numbers are below 70, then possibly you might actually need a bedtime snack.
I'm going through the same thing myself...all of a sudden, for the past several weeks, my morning numbers have been getting higher and higher. Unfortunately, I take sleep medication, so getting up to test in the wee hours hasn't been successful yet...but I will keep trying. I'm pretty certain it's Dawn Phenom, but then I did have one morning when I woke up at 95...just to confuse the issue, I guess!
Every now and then I test if I wake up around 2 or 3 or 4am to visit the washroom. I am never low, usually 100ish. So I am sure it's dawn phenomenen. I get the rise with the peak at around 7AM
I have tried every combination of snack before/type of snack/excercise before bedtime......nothing helps or hurts.
It's more random, but for several days in a row. I will be 100 one week, 110 the next, 120 the next, back to 110, usually for at least a week. I don't see 100 one day, 120 the next....
I had one bought of really bad few weeks, where I was getting 140s. I also had 1/3 of my body covered in poison ivy. Sure enough things came back to normal when the poison ivy went away.
I ended up seeing the doc. He says I shouldn't muck with my "circadian rhythm". He said no to the insulin. My 1ac is good enough he says. "just continue doing what you're doing", which is ok, I guess.
He talked a little about Januvia. He said it would help prevent absoption of glucose while eating. I can do the same with carb counting and low GI so I said no thanks. It would do little for my fasting.
Apparently a bit of wine at night helps morning fasting levels. I like this theory and am sticking to it :-)
He had never heard of the GAD antibody test, so I guess I will continue to experiment on my own. If I would have asked to see an Endo he probably would have got very miffed.
what kind of sleep medication are you taking ? Maybe that has something to do with it. I took some Melatonin at one point and it made my numbers go coocoo.
